Abstract: Microbial cell aggregates with high penicillin acylase content consist of enzyme contg. microorganism cells chemically bonded, to each other or to cells of different organisms, by a bi- or poly-valent aldehyde, esp. glutaraldehyde. The carrier cells can be native and/or physically, chemically or biologically modified cells, or their insoluble fragments of various morphology. These cells or fragments are pref. in the form of fibres, spheres, ellipsoids etc. of dimension 1-1000 mu m, or in forms prod. by spontaneous or artificial autolysis or by other cell-destruction processes.

Title: Milk processing system - by separate treatment of skimmed milk with low and cream with high germ count
Inventor: SCHILHABEL WILFRIED DIPL ING
IPC: A01J11/10
Filed: 1978-09-11
Abstract: In a process to produce milk with a low germ count and a set fant content, the raw milk is stored, or revolved around a vertical axis to separate a high-fat cream from a low-fat skimmed milk. The two parts are separately treated subsequently. This causes a minimum change in the raw milk properties but adjusts the fat content to the desired figure and the germ count to a minimum.
Patent DE-2840455-A1 (DE)

Title: Long gauze belt for paper-making - maintains density of running surface warp and increases ratio pitch warp wire diameter
Inventor: HENKE HEINZ DIPL ING
IPC: D21F1/10
Filed: 1979-02-26
Abstract: A woven fabric of metal wire having a twill construction, in which the warp wires are cranked around the weft wires, forms a long belt for a paper making machine. On the paper side, there is a single wire binding, and the warp wires lie against each other. Whilst the density of the warp wires is maintained on the running side, the weft wires are also cranked, and the ratio of the spacing of the binding warp wires to the warp wire diameter is increased. The construction may be a four twill arrangement. The design maintains the longer life achieved by the means outlined in DT2530110, whilst at the same time it produces a paper without marking which prints much better.

Title: Dust filter for mines - with fluid conveyor chute taking wetted dust to pump for discharge
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D46/42
Filed: 1979-04-14
Abstract: The risk in a dust (esp. coal) filter of explosion due to friction produced, caused spark when a screw conveyor is used to discharge the collected dust is eliminated by introducing compression air to a fluid conveyor chute along the bottom of the filter and conveying the dust to a pump. A copious supply of water to the pump ensures that the dust is intimately wetted. The slurry can then be sprayed over the coal which is ready to be hauled out of the pit without any hazard. To ensure a slanting position for the chute, a wedge or adjustable feet can be used as support.

Title: Amorphous metals or alloys used for storing gas - esp. hydrogen used as fuel in IC engines
Inventor: KOPMANN GERD DIPL ING
IPC: C01B3/00
Filed: 1979-05-16
Abstract: The solid substances used consist of amorphous metals which are also known as metallic glasses, and they include metastable microcrystalline metals and alloys. A melt of suitable (but unspecified) compsn., which has an exponential solubility for gas, is quenched by being brought into contact with a cold substrate so a cooling speed of ca. 10 degrees K. per second is achieved to solidify the melt. The low packing density of the amorphous metals or alloys permits much higher storage of H2 than conventional metals currently being used for this purpose.

Abstract: Prodn. of 3,4-dicyano 1,4-diamino anthraquinones of formula (I) comprises reacting the corresp. 2- or 2,3-di-sulphonic acids (II) or their salts with a cyanide ion source using as reaction medium N-methyl-formamide or pref. formamide. (R is H, or opt.substd. (cyclo)alkyl; and X is H or sulphonic acid gp.). Opt. the reaction is carried out in the presence of an oxidising agent, and opt. also heavy metal catalyst and acid acceptor. The cpds. (I) where R is opt.substd. cycloalkyl are new.. The cpds. (I) are dyes and dye intermediates. By using these specific solvents, (I) are obtd. in improved yields with very high purity, i.e. below 3% of the mononitrile cpds. (which shift the bright, greenish-blue colour of pure (I) to less desirable reddish shades). Also less solvent is used so space-time yields are better.

Title: Arc monitor for high frequency induction coil - with sensor cutting power repeatedly in presence of free charge carriers (BE 13.6.80)
Inventor: GREGORY ROBERT OSCAR
IPC: G01R31/00
Filed: 1979-12-13
Abstract: A zone melting furnace for semiconductor rods is equipped with a feeler close to the high-frequency heating coil which responds to the presence of an electric arc. An amplifier circuit causes the current supply to interrupt briefly without stopping the melting process. If several (4 or 5) interruptions fail to cure the defect, the power is cut off and can only be restarted manually. This safeguards the plant against the destructive effects of electric arcs and monitors the conditions which lead to the appearance of electric arcs between coil and rod or between parts of the coil.

Patent DE-3017338-A1 (DE)
Title: HV transformer for X=ray generator - has potential plate of electrical resistance material surrounding primary winding
Inventor: BAUMANN HEINZ ING GRAD
IPC: H01F27/36
Filed: 1980-05-06
Abstract: The choice of electrical resistance material for the potential plate of the high-voltage transformer means that eddy currents and heating of the potential plate are reduced. The distance between the secondary winding (3) and the potential plate (4) is so great that there is sufficient high-voltage insulation. The heating caused by the eddy currents arising from leakage fluxes in the transformer is kept low because of the electrical resistance material of the plate, which is e.g. austenitic steel or a chrome-nickel alloy.
